Fe2O3 + H2 =
FeO + H2 =

Answer 1

3Fe + C -->Fe3C
Fe + 4HNO3(разб., гор.) = Fe(NO3)3 + NO + 2H2O

Comments

Fe + 6HNO3(конц.) = Fe(NO3)3 + 3NO2 + 3H2O

---

FeO + H2 = Fe + H2O

---

Fe + H2SO4(разб.) = FeSO4 + H2

---

2Fe + 6H2SO4(конц.) = Fe2(SO4)3 + 3SO2 + 6H2O

---

Fe2O3 + 3H2 = 2Fe + 3H2O

---

3H2SO4 + 2Fe(OH)3 = Fe2(SO4)3 + 6H2O
